My G602 died due to Logitech's infamous double-click issue. :(
I've been fine with the G502 X Lightspeed (which should avoid said double-click issue due to optical switches) and some more efficient button use to compensate for the fewer side buttons.
I looked it up (because I had already replaced switches on previous mice) and the fix required carefully removing a rubber cover that is glued in place and tears if you look at it wrong. It also requires removing the skates at the base, which means buying new ones. Even if you do that, the switch is very hard to access. Easily a 60+ minutes job.
I bought the switch thinking it was a 2 minute job and it’s still sitting on a closet for when I have the patience to do it.
Its very easy to source switches, soldering kit and skill curve for this particular repair is short. Plus you can even end up with better performing mouse switches
